Re: How to differ mouse click and drag?
It is very unlikely that mouse up is sent without mouse move .... specially
if a user is performing this activity .... the cursor may misplace every
time down and up (simply click) is performed and this generates mouse move
events ..... i suggest u one thing ... take care of this programmatically
....... and if u are going to provide both click and drag functionality for
some window ... consider using dblclick instead of click ... this will even
make users life a bit easier ......

I am having a problem regarding mouse capture. I am capturing mouse
events in my LBUTTONDOWN Handler but i am unable to differ between
click (Mouse down and UP) and drag(Mouse down -> move -> up).
When i am expecting single click windows fires mouse move too. at
first time it runs fine but for subsequent clicks it gives me msg
"Mouse L-Button UP, After Mouse Move.".
What to do now?
Following is my code in which i am capturing mouse events on
void CMouseCaptureView::OnLButtonDown(UINT nFlags, CPoint point)
CWnd *pwnd = AfxGetApp()->GetMainWnd();
HWND hwnd = pwnd->GetSafeHwnd();
bMove = TRUE;
pt = msg.lParam ;
if(hwnd != GetCapture()->GetSafeHwnd() )
bMove = FALSE;
AfxMessageBox("Mouse L-Button UP, After Mouse Move.");
AfxMessageBox("Mouse L-Button UP.");
}//End of switch
// release the mouse (if we still own it)
if (GetCapture() == this) ::ReleaseCapture();
}//End of For
